AKA = "Reactive"
Who's the largest of the WBCs in the peripheral blood?

Who's major function is phagocytosis?
(attack tumor cells)
Increased numbers of what WBC are seen in a variety of chronic infections?
Who's the best WBC?
Who contains a nucleus that is similar to that of neutrophils, but the chromatin is usually not as coarsely clumped?
(bi-lobular and dark)
Who's shape of the granules varies considerably among species?
Who's cytoplasm contains granules that often vary in size with small and large within the same cell, stain less intensely than others, they are usually dark red and round in Canines?
Who's cytoplasm contains granules that are small, rod shaped, and numerous in Felines?
Who's capable of phagocytosis, but their function is in the modulation of the immune system?
